Patients with chronic obstructive pulmonary disease (COPD) experience a high risk for psychological distress. Understanding what factors contributing to this risk is vital for developing effective interventions to address COPD-related psychological distress. To examine psychological distress and its associated factors in COPD patients in China. This is a cross-sectional study. Using cluster random sampling, 351 COPD patients participated in and completed a questionnaire survey from June 2021 to January 2022. Instruments used in this research included a self-designed social-demographic questionnaire, the Kessler Psychological Distress Scale (K10), the COPD Knowledge Question, the Type D Personality Scale (DS-14), the COPD Assessment Test (CAT), and modified Medical Research Council Dyspnea Score (mMRC). Multivariate linear regressions were used in the final analysis. Among 351 COPD patients, 307 (or 87.5%) had psychological distress. Our univariate analysis indicated that psychological distress scores were significantly associated with monthly household income (F = 2.861, P < 0.05), exercise frequency (F = 4.039, P < 0.01), type D personality (t = 5.843, P < 0.01), years with COPD (r = 0.156, P < 0.01), frequency of acute exacerbation (r = 0.114, P < 0.05), mMRC score (r = 0.301, P < 0.01), and CAT score (r = 0.415, P < 0.01). Our final multivariate linear regression showed that exercise frequency (coefficient = -1.012, P < 0.01) was an independent protective factor of psychological distress in COPD patients, while type D personality (coefficient = 3.463, P < 0.001), mMRC score (coefficient = 1.034, P < 0.001) and CAT score were independent risk factors (coefficient = .288, P < 0.001). No relationship was observed between psychological distress and knowledge of COPD. Psychological distress is commonly presented among COPD patients in China. Findings from this study suggest promoting and increasing frequency of exercise will be beneficial in reducing psychological distress among COPD patients. This study also highlights the importance of assessing personality type, dyspnea, and impact of COPD on daily living for preventing and managing psychological distress due to COPD. In addition, Given the high rate of psychological distress among COPD patients, policymakers should consider making mental health resources easily available and accessible to this vulnerable population.
患者患有慢性阻塞性肺疾病（COPD）经历了心理困扰的高风险。了解促成这种风险的因素对于开发有效的干预措施来解决 COPD 相关的心理困扰至关重要。检查心理困扰及其在中国 COPD 患者中的相关因素。这是一项横断面研究。使用聚类随机抽样，351 名 COPD 患者参加并完成了 2021 年 6 月至 2022 年 1 月的问卷调查。本研究使用的工具包括自我设计的社会人口学问卷、凯斯勒心理困扰量表（K10）、COPD 知识问卷、型人格量表（DS-14）、COPD 评估测试（CAT）和改良医学研究理事会呼吸困难评分（mMRC）。最终分析采用多元线性回归。在 351 名 COPD 患者中，有 307 名（或 87.5%）有心理困扰。我们的单因素分析表明，心理困扰评分与月家庭收入（F=2.861，P<0.05）、运动频率（F=4.039，P<0.01）、型人格（t=5.843，P<0.01）、COPD 病程（r=0.156，P<0.01）、急性加重频率（r=0.114，P<0.05）、mMRC 评分（r=0.301，P<0.01）和 CAT 评分（r=0.415，P<0.01）显著相关。我们最终的多元线性回归显示，运动频率（系数=-1.012，P<0.01）是 COPD 患者心理困扰的独立保护因素，而型人格（系数=3.463，P<0.001）、mMRC 评分（系数=1.034，P<0.001）和 CAT 评分（系数=0.288，P<0.001）是独立的危险因素。心理困扰与 COPD 知识之间没有关系。心理困扰在中国 COPD 患者中很常见。这项研究的结果表明，促进和增加运动频率将有助于减少 COPD 患者的心理困扰。这项研究还强调了评估人格类型、呼吸困难和 COPD 对日常生活的影响对于预防和管理 COPD 引起的心理困扰的重要性。此外，鉴于 COPD 患者的心理困扰率较高，政策制定者应考虑为这一弱势群体提供方便和可及的心理健康资源。
